DOOR SOUND INSULATION REPAIR AREA

Repair in the event of damaged sound insulation or leakage
  • Cut the butyl rope between the sound insulation and the inner door panel with a sharp knife
  • After the repair is finished, position a new butyl rope 3 mm directly on the original adhesive bead
  • Heat the butyl bead with a standard hot air blower until the butyl rope strings when touched slightly. Do not damage the sound insulation in the process
  • Press down with special tool 51 0 300 . Perform this work extremely carefully because the increased amount of adhesive requires pressure of ≥ 20 N/cm2 (compared to firm thumb pressure ~ 30 N/cm2 )
  • Visually check the adhesive bead and its compression (no capillaries or broken adhesive bead permitted)
  • In the cases mentioned, the complete sound insulation must be replaced. After removing the sound insulation, removal all butyl remnants from the inner door panel. Apply 6 mm butyl rope to new sound insulation
  • Press down with special tool 51 0 300 to ≥ 20 N/cm2 compare to firm thumb pressure ~ 30 N/cm2 )
